. MANTLE- UP'POBTI I mrweeaem Specification of Letters Patent. Application filed April 2, 1906- Serial No. 809,566-

Patented Feb. 5, 1 907.

at Chicago, in the county of Cook and State. of Illinois, have invented a'certainnew and= useful Improvement in Mantle-Supports, of

' which the following is a specification.

My invention relates to mantle-caps designed for use in connection with gas burners 'to hold the mantle in inverted position.

- The object of the invention is to provide a mantle cap or holder which may be readily attached to and detached from a burnertip and when attached will prevent vertical movementof the cap and accidental dislodging thereof from the burner-ti This object is a tained by the form of evic'e shown in the accompanying drawin s, in which Figure l is a general assem ly view, chiefly in central vertical section, showin cap,mantle, burner, and exterior globe. ig. 2is a side view of the improved cap or holder. Fig. 3 is a plan sectional view taken on line 3 3,Fi g. 1. Fig. 4 is a fra mentary perspective view showing one of t 1e lugs which proj ects from the burner-tip.

Similar numerals refer to similar parts throughout the several views.

The tip 1 is cylindrical in form and has a number, usually three, 111 s 2 projecting horizontally and radially t erefrom. At the edges of one or more of these lugs are flanges 3 for retaining the clips 4 of the mantle-cap in position.

The mantlc-ca proper consists of an'annular plate 5, Whic is centrally apertured, so that it may fit around the burner-tip l Without binding the same, but substantially with out lateral )lay. Practically none of the gases of com ustion pass between said plate and said tip,the tip deflecting them, so that they pass up around its outer edge. EX- tending radially inwardly from the outer portion of said plate at dill'crent points on the periphery are the aforesaid clips 4, which are I ada )ted to support the cap in osition upon sai tip. Inasmuch as plate 5 ies below the lugs 2 and the cli s 4 lie. above them, vertical play is prevcnte thereby assuring permanence and stability of the cap and mantle upon. the tip. Theparts are so designed that I ve just enoug rtical play is ossibleto permit the clips 4 from beingralsed clear of the hinges 3 on the lugs 2. I

i The mantle 6 is adapted to he slipped over the exterior surface of a mantle-ring 7, which of said ring is preferably 5 by means of the hangers 8. The diameter approximately equal to the outside diameter 0 said plate. The hangers are preferablythree in number,

in the best form of device the ring 7 and hangers 8, clips 4, will be formed of a single piece with plate 5, the whole being stamped out of a single sheet of metal. In order to "afford sufiicient passage for the escape of the gases of combustion, the .ring 7 and consequently the upper edge of the mantle 6 are 10- cated at a considerable distance below plate 5.

The gases therefore escape laterally outwardly over the upper edge of the mantle at a point below plate 5. The preferred manner of attaching the mantle to ring 7 is to have said ring formed with a peripheral and horizontal groove therein, which thus forms a pocket or seat in which an asbestos or'similar cord or wire may lie, the mantle edge being held between such cord or wire and the exterior surface of said ring.

One of the advantages of this device is the fact that it remains firmly in position upon the burner-tip, and yet does not have to be rotated but a very slight amount in being attached and detached. In the design shown less than one-eighth of a complete turn is necessary to attach or detach the cap, and when once attached vertical play is substantially prevented.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a burner the combination of a burnerjecting laterally therefrom; and a mantlecap consisting of an annular plate circularly apertured to lit snugly over said tip to prevent lateral play, clips projecting upwardly from said plate and inwardly so as to rest upon said lugs, said lugs-being thereby located between said plate and clips for preventing vertical play of said cap, and said cap also having a ring for supporting the is rigidly supported from and beneath plate tip having a cylindrical wall and lugs promantle at a distance below said plate suflicient to afford an escape-passage between said plate and the top of the mantle.

In witness whereof I have hereunto subscribed my name in the presence of two wit,-

nesses. v
